The following description gives an overview for the different products and concepts of the Tinkerforge building block system. A detailed description of the functions and offered APIs can be found in the documentation of each product.
Our products are divided into five different categories:
This tutorial explains of how everything works together.
Bricks are 4 x 4cm (1.57 x 1.57") modules that can be controlled by devices, such as (embedded) PCs, over their Mini-USB connector. Every Brick basically performs one task. There are Bricks that perform complex sensor tasks (e.g. the IMU Brick 2.0), communicate (e.g. the Master Brick) and drive motors (e.g. the DC Brick).
With Bricklets the features of Bricks can be extended. Dependent on the Brick it has none, two or four connectors for Bricklets.
Bricks can be assembled into a stack (see description of stack concept). The USB interface of a Master Brick can be replaced by Wi-Fi, Ethernet or RS485 using Master Extensions. In conjunction with the stack concept all Bricks and Bricklets can be controlled by Wi-Fi or Ethernet instead of by USB.

Bricklets can be used to extend the features of Bricks. There are Bricklets to measure physical quantities such as rotation, voltage, current and ambient light as well as Bricklets for control purposes such as switching relays, digital input/output and alphanumeric output on LCDs.
Unlike Bricks, Bricklets have no fixed size. Each Bricklet has the minimum size possible. Each Brick has up to four connectors for Bricklets. Bricklets can be controlled over the USB connection of the connected Brick.

If a Master Brick is used on its own or in a stack, communication is done over its USB interface. Master Extensions extend Master Bricks by other communication interfaces. There are cable based (RS485, Ethernet) and wireless Master Extensions (WIFI) available. Instead of over USB, Bricks and Bricklets can be controlled over Wi-Fi or Ethernet using the corresponding extension. RS485 can be used to interconnect Bricks and Bricklets over larger distances.
From a programming perspective the different interfaces are transparent. A stack with a Master Extension behaves as if every Brick in the stack is directly connected to the PC over an USB connection.
This means: You can develop an application with all modules independently connected to the PC over USB. Later you can stack these modules together to stacks, add Master Bricks and cable based or wireless Extensions and you can run the previously written code without any changes.
There is an extra section for discontinued Extensions.

|RS485||Cable based RS485 connection between stacks|
|WIFI||Wireless Wi-Fi connection between stack and PC|
|WIFI 2.0||Wireless Wi-Fi connection between stack and PC|
Bricks and Bricklets can be powered by the USB connector of the Brick. Stacks can also be powered by the master of the stack over its USB connection. This option is limited by the USB specification to 500mA. A large stack may need more power.
To provide greater currents, Power Supplies are available. These modules power the stack and can additionally be used to supply the power for driver Bricks (e.g. the DC Brick). Power Supplies have the same size as Bricks and are stacked in at the bottom of the stack.
|Step-Down||Powers a stack of Bricks with 5V|
Bricks can be stacked. A Master Brick (as the lowermost Brick) is responsible for the communication between all boards within the stack. This master routes the messages between the boards in the stack and the controlling device. This way only one USB connection is necessary to control all Bricks and Bricklets of a stack. For the user, the stack behaves as if all Bricks were connected separately over USB with the device. The stacking tutorial gives more information about how to use stacks.
A general description of the programming interface can be found here. An overview of the API bindings for each programming language is given here. The API of each product, including examples in any supported programming language, can be found on each product document page.
